What Makes a River Flow Faster or Slower?

Imagine a river like a line of people passing a ball. If there are only a few people, the ball moves slowly, that's like a lazy river. But if lots of people join in, the ball zooms through, and that's a fast-flowing river! A river flows faster when it has more water or less space to move in, just like how you can run faster on a straight path than through a crowded hallway.

Examples

  1. When it rains heavily, the river gets faster because more water flows into it.
  2. A narrow stream can feel like a wild river if you're walking through it, that’s because its shape makes the water flow quicker.
  3. River speed changes when leaves and dirt pile up in a riverbed, slowing things down like traffic jams.
